AOI tracing system

Abstract

The invention discloses an AOI tracing system which comprises a main control module, an information acquisition module, a data uploading module, a data duplicate checking module, a server module, a query module, a query optimization module and a signal transmission module. The main control module is interactively connected with the signal transmission module, and the query optimization module is interactively connected with the signal transmission module; the server module is in interactive connection with the signal transmission module, the information acquisition module is connected with thedata uploading module, and the data uploading module is in interactive connection with the data duplicate checking module; in the using process, the information collecting module is arranged to collect SPC data, time information, bar codes, program names, part position information and bad phenomenon information, the information is uploaded to the server module to be stored and backed up, AOI datacan be inquired through time, bar codes, program names, part positions, bad phenomena and other information, and adverse risk batches are reduced, and the rework cost is reduced.

Description

technical field [0001] The invention relates to the technical field of AOI traceability, in particular to an AOI traceability system. Background technique [0002] AOI is an equipment based on optical principles to detect common defects encountered in welding production. AOI is a new type of testing technology emerging, but it is developing rapidly. Many manufacturers have introduced AOI testing equipment. When automatic testing, the machine Automatically scan the PCB through the camera, collect images, compare the tested solder joints with the qualified parameters in the database, and check out the defects on the PCB after image processing, and display / mark the defects through the display or automatic signs for repairing by maintenance personnel , using high-speed and high-precision visual processing technology to automatically detect various mounting errors and welding defects on PCB boards. The range of PCB boards can range from fine-pitch high-density boards to low-densi...

AI Technical Summary

Problems solved by technology

[0003] In the actual production process, in most cases, it is necessary to query the AOI data through the part location and defect information, judge the risk batch, and judge the responsibility of the customer complaint defective product through the entire board image information, but the existing AOI only Provide data query based on barcode, for this purpose, propose AOI traceability system
